[en] We study strange and charmed baryon productions, π + p → K(D) + Y(Yc), where Y(Yc) is a strange(charmed) baryon of a ground or an excited state. We propose a new production mechanism where two quarks in the baryon participate in the reaction (two-quark process), which enables excitation of both λ- and ρ-modes of the baryons. To deal with the two-quark process, we consider the ’t Hooft six-quark interaction from the instanton model. We study production rates in relation with the structure of charmed baryons for forward-angle scattering. (author)
